Adaptive loss of tRNA gene expression leads to phage resistance in a marine Synechococcus cyanobacterium.

Synechococcus is a significant primary producer in the oceans, coexisting with cyanophages, which are important agents of mortality. Bacterial resistance against phage infection is a topic of significant interest, yet little is known for ecologically relevant systems. Here we use exogenous gene expression and gene disruption to investigate mechanisms underlying intracellular resistance of marine Synechococcus WH5701 to the Syn9 cyanophage.

A unified model for droplet receding contact angles on hydrophobic pillar, pore, and hollowed pillar arrays.

Hypothesis: Current models for receding contact angles of Cassie-Baxter state droplets on textured hydrophobic substrates are applicable only to a specific structural type, e.g., pillar (above which a droplet has isolated contact line and continuous liquid-vapor interface) or pore (continuous contact line and isolated liquid-vapor interface), signifying a lack of universality.

Photonic Quantum State Tomography Using Free Electrons.

The tomography of photonic quantum states is key in quantum optics, impacting quantum sensing, computing, and communication. Conventional detectors are limited in their temporal and spatial resolution, hampering high-rate quantum communication and local addressing of photonic circuits. Here, we propose to utilize free electron-photon interactions for quantum state tomography, introducing electron homodyne detection with potential for femtosecond-temporal and nanometer-spatial resolutions.

Stochastic morphological swings in regeneration: A manifestation of noisy canalized morphogenesis.

Animal morphogenesis, the development of an organism's body form, is commonly perceived as a directed and almost deterministic process. However, noise and stochastic fluctuations are ubiquitous in biological systems. The questions on the role of fluctuations in morphogenesis and what ensures the robustness of this process under noisy conditions remain elusive.

Density functional study of physisorption of H molecules on scandium and yttrium decorated C fullerene: prospect for hydrogen storage.

Context: Hydrogen storage in porous nanostructured compounds have recently attracted a lot of attention due to the fact that the underlying adsorption mechanism and thermodynamics provide suitable platform for room temperature adsorption and desorption of H molecules. This work reports the findings of a study on the reversible hydrogen storage capacities of Sc and Y decorated C fullerene, conducted using dispersion-corrected density functional theory (DFT) calculation. The transition metal (TM) atoms, such as Sc and Y, are identified to attach to the C-C bridge position of the C fullerene through non-covalent closed-shell interactions.

This study reviewed the recovery of humic substances (HS) from anaerobic digestate of sludge as a potential fertilizer, focusing on the quantification of HS, the efficiency of HS recovery, and its interaction with pollutants. The potential pitfalls of current misunderstanding for HS quantification in sludge were pointed out. HS present in sludge showed potential to be used as a fertilizer, which solubilized insoluble phosphates for enhanced soil fertility.

Single-nuclei RNA-sequencing fails to detect molecular dysregulation in the preeclamptic placenta.

Introduction: Single-cell RNA-seq (scRNA-seq) revolutionized our understanding of tissue complexity in health and disease and revealed massive transcriptional dysregulation across placental cell classes in early-onset, but not late-onset preeclampsia (PE). However, the multinucleated syncytium is largely inaccessible to cell dissociation. Nuclei isolation and single-nuclei RNA-seq may be preferable in the placenta; not least considering compatibility with long-term tissue storage.

Vimentin is a ubiquitination and degradation substrate of the ubiquitin ligase KPC1.

The ubiquitin proteasome system (UPS), driven by ubiquitin as a degradation signal, eliminates, in a highly specific manner, 'abnormal' proteins and proteins that completed their function. This process involves a hierarchical cascade of E1, E2, and E3 enzymes. The E3 ubiquitin ligases, act as specific receptors that bind their cognate substrates.

The Value of ROH Metrics for Predicting Morbidity: Insights From a Large Cohort Analysis of Chromosomal Microarray.

This retrospective cohort study aimed to define the optimal Regions of Homozygosity (ROH) size cut-offs for prediction of morbidity, based on 13 483 Chromosomal Microarray Analyses (CMA). Receiver operating characteristic (ROC) curves were generated, and area under the curve (AUC) was used to assess the predictive capability of total ROH percentage (TRPS), ROH number and ROH segment size in distinguishing between healthy (n=6,196) and affected (n=6,839) cohorts. The metrics were examined for telomeric and interstitial segments, distinct TRPS categories, and across different ancestral origins.

LieRHRV system for remote lie detection using heart rate variability parameters.

The standard polygraph, or lie detector, is limited by its reliance on average heart rate, subjective examiner interpretation, and the need for direct subject contact. Remote photoplethysmography (rPPG) offers a promising contactless alternative, by using facial videos to extract heart rate variability (HRV). We introduce "LieRHRV," a remote lie detection algorithm based solely on extracted HRV parameters.

Addressing the role of surgery in brain tumour trials: A report from the neurosurgery committee of the EORTC brain tumour group.

The Brain Tumor Group (BTG) of the European Organization for Research and Treatment of Cancer (EORTC) conducts academic clinical trials and translational research to improve clinical management of patients with primary and secondary brain tumors. The EORTC BTG has traditionally played an important role in providing evidence and thus advancing the field, albeit with a main focus on radiotherapy and pharmacotherapy in gliomas. Although examples of well-designed neuro-oncological surgical trials can be found, evidence in surgical neuro-oncology predominantly includes data from uncontrolled prospective series or retrospective cohorts.

Collective Interactions of Quantum-Confined Excitons in Halide Perovskite Nanocrystal Superlattices.

Collective optical properties can emerge from an ordered ensemble of emitters due to interactions between the individual units. Superlattices of halide perovskite nanocrystals exhibit collective light emission, influenced by dipole-dipole interactions between simultaneously excited nanocrystals. This coupling changes both the emission energy and rate compared to the emission of uncoupled nanocrystals.
